Use super shark battery on 2 bikes

I am thinking of converting another one of my bikes to an e-bike and would like to use the same 52V super shark battery as I use on my first e-bike. Do vendors sell just the bike mounted cradle/socket? Are they somewhat standard or do you need to get one from the original battery vendor?

Well, I couldn't find anyone selling just the cradle so I just ordered an empty Super Shark case from AliBaba. Comes with a cradle, of course.
